Systematic errors in an isoperibol calorimeter of a widely-used design, amounting to about 0.5 percent of the endothermic enthalpy of solution of SRM 1655 (KCl) in HO, were found to be the result of errors in heat leak corrections due to inadequate stirring and commonly used calorimetric procedures. Other systematic errors were found in measurements of the enthalpy of solution of the exothermic reaction of tris(hydroxymethyl)aminomethane in aqueous HCl solution. Recommended procedures are summarized.
在一种广泛使用的设计的等温环境热量计中发现了系统误差,该误差相当于SRM 1655(KCl)在水中溶解的吸热焓的约0.5%,这是由于搅拌不足和常用量热程序导致的热泄漏校正误差造成的。在三(羟甲基)氨基甲烷在盐酸水溶液中的放热反应的溶解焓测量中也发现了其他系统误差。总结了推荐的程序。
